Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504504, here are decompositions:

11 + 31504493 = 31504504
23 + 31504481 = 31504504
131 + 31504373 = 31504504
137 + 31504367 = 31504504
401 + 31504103 = 31504504
467 + 31504037 = 31504504
491 + 31504013 = 31504504
587 + 31503917 = 31504504

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.184.120.

Address: 1.224.184.120
Class: public
IPv4-mapped IPv6: ::ffff:1.224.184.120

Public, routable address (assignable to a host on the internet).

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
